Abstract

Coolseason food legumes faba bean chicLpea and lentils are mostly grown in rainfed dryland systems
because of many virtues such as high protein content atmospheric nitrogen fixation and low carbon and
water foot prints When grown in rotation with cereals these crops also act as a break in disease cycles
However annual and parasitic weeds are the major production constraints in this group of crops because
of slow initial growth and being poor competitor to weeds Manual weeding is laborious and time
consuming Preernergence herbicide application is effective but application of postemergence
herbicides is not safe due to crop sensitivity In addrtion food legumes are heavily infestedby Orobanche
crenata in North and East Africa Faba bean cultivars with resistance to orobanche have been developed
in Eg1pt Ethiopia and Tunisia but the resistance is partial and consequently there is a need to develop
integraled management with herbicide tolerance such as low dosage of Glyphosate Sources for
resistance to different herbicides in faba bean chiclcpea and lentils were identified At ICARDA 289
mutant lines of faba bean were screened against high dosage of Glyphosate resulting in identification of
two lines Mu38 and Mu418 as tolerant to 1600 g ailha Similarly 300 faba bean lines were screened
against various postemergence herbicides with different modes of action like MetribuzinImazelhapy
and Oxyflourfen and 10 lines were found highly tolerant to Imazethapyr and 8 to Metribuzin ln lentil
353 genotlpes were screened for tolerance to Metribuzin and Imazethapyr Highly tolerant genotlpes
identified included ILL8112 iLL5988 ILL8009 andILL4994 for Imazethapyr and ILL1005 ILL0462
ILL553l ILL6434 ILL0195 GCP10 and 065 5311002 for Metribuzin Similarly in chickpea
screening of 49 genotypes including germplasm accessions and advanced breeding lines against
ImazethJpyr and Metriburin and resulting in identification of 10 genotypes tolerance to Imazethapyr and
two for Metribuzin These sources are used in breeding program to transfer genes for resistance to
cultivars grown in different agro ecological zones
